treewide: remove editor modelines and cruft The section "19) Editor modelines and other cruft" in Documentation/process/coding-style.rst clearly says, "Do not include any of these in source files." I recently receive a patch to explicitly add a new one. Let's do treewide cleanups, otherwise some people follow the existing code and attempt to upstream their favoriate editor setups. It is even nicer if scripts/checkpatch.pl can check it. If we like to impose coding style in an editor-independent manner, I think editorconfig (patch [1]) is a saner solution.

ocfs2/dlm: Add message DLM_QUERY_REGION Adds new dlm message DLM_QUERY_REGION that sends the names of all active heartbeat regions. This message is only sent in the global heartbeat mode. If the regions in the joining node do not fully match the ones in the active nodes, the join domain request is rejected.
